In general, success in a marathon depends on your bio-chem treating you right; altitude, heat, humidity, cold and rain etc., affects us all differently. No matter how talented, prepared and game you are, if your bio-chem is affected by the conditions more, you are operating at a disadvantage. I would not be surprised to hear that the cold moist air affected some of the elite athletes.
Bio-chem is a scientific discipline, not a biological attribute.
